Permalink markers not visible for targets with custom labels

[pocek]

Furo has a code like this:

h1,
h2,
h3,
h4,
h5,
h6
  :target > &:first-child > .headerlink
    visibility: visible

The problem is, if section has a custom label (like in Cross-referencing arbitrary locations), the header is not a first child anymore, so the marker is not visible. I currently patch this with a CSS:

/* Fix for custom labels */
:target > h1:nth-of-type(1) > .headerlink,
:target > h2:nth-of-type(1) > .headerlink,
:target > h3:nth-of-type(1) > .headerlink,
:target > h4:nth-of-type(1) > .headerlink,
:target > h5:nth-of-type(1) > .headerlink,
:target > h6:nth-of-type(1) > .headerlink {
    visibility: visible;
}

The key here is to use :nth-of-type(1) instead of :first-child.

Thanks for the report! I'm pretty sure I investigated this because of your report, and never got around to actually writing this comment here. :)
